Overview
ISO/TR 22400-10:2018 is a Technical Report in the ISO 22400 series that provides practical, example-based guidance for acquiring and processing data used to calculate manufacturing Key Performance Indicators (KPIs). Intended to be applied together with ISO 22400‑2, this document explains the operational sequence of data acquisition, work unit log structure and the step‑by‑step determination of KPI elements so organizations can reliably compute KPIs for production control and monitoring.
Key topics and technical requirements
- Operational sequence of data acquisition: clear descriptions of how event notifications and timestamps from work unit logs are used to derive KPI input elements.
- Work unit logging: definitions and examples of the work unit log (event recording with time stamps) and associated time categories such as Planned Shut Down Time (PSDT), Planned Down Time (PDOT), Actual Productive Time (APT), Actual Unproductive Time (AUST) and Actual Downtime (ADET).
- KPI calculation examples: worked examples showing how to compute KPI elements and final KPIs for:
- Work unit scope (e.g., Utilization, Setup ratio, Technical efficiency, Availability, Effectiveness, Quality ratio, OEE, NEE)
- Production order and sequence scope (e.g., Throughput rate, Production process ratio, First Pass Yield, scrap/rework ratios)
- Asset reliability metrics (MTBF, MTTF, MTTR)
- Energy KPIs (direct energy consumption/net energy consumption effectiveness and efficiency)
- Formulas and aggregation rules: illustrative calculations (for example, OEE = Availability × Effectiveness × Quality ratio) and guidance on aggregating piece counts, energy and time across production orders and work units.
- Data quality considerations: emphasis on the need for serialized/unique product flow for FPY calculations and the relationship between first-test evaluations and final quality metrics.
Practical applications and users
ISO/TR 22400‑10:2018 is useful for:
- Manufacturing operations managers and plant engineers implementing KPI-based performance monitoring.
- MES/SCADA and automation integrators defining event logging and data schemas for KPI derivation.
- Industrial/quality engineers calculating OEE, FPY, scrap and rework metrics for continuous improvement.
- Maintenance planners using MTBF/MTTR calculations to prioritize reliability efforts.
- Energy managers measuring direct and net energy efficiency at line or work‑unit level.
Practical uses include configuring work unit logs, mapping MES/PLC events to KPI elements, validating KPI calculations for dashboards and benchmarking production performance.
